Description

Built-in switch with plug connection for devices =============================================== The task was to develop a built-in changeover switch with plug connection for devices that optionally switches two heating elements in parallel or in series by changing the position of the actuating element, in which the current flow must be interrupted or closed via a heat regulator.

A slide switch was chosen as a suitable design, its 5 contact connections are arranged so that the required conditions through Moving a lever in a known way, in two switching positions is achieved.

The innovation consists of two movable contact pieces (a) that in recesses (b) of a slide (c) under pressure from one or more springs (d) are stored, and on fixed contacts (j) with terminal lugs (k) in a Plate (i) are firmly attached, act. The slide (c) has the shape of a 4-sided lying cuboid body and supports longitudinally displaceable in the box-shaped cavity (e) of the switch housing (f) and is simultaneously in it guided. The actuator (g) (a small one) is firmly connected to the slide (c) Lever) which protrudes through a slot (h) in the switch housing (f) and which can move in it to switch. The cavity (e) of the switch housing (f) and the slide (c) stored in it becomes the one that carries the fixed contacts (j) Plate (i), covered and sealed.

Switch housing (f), slide (c) and plate (i) are made of molded insulating material manufactured. In the walls of the switch housing (f) there are two connector pins (l) attached over the front as well as the back of the switch housing (f) protrude.

On the front they are used to connect to a device plug.

On the back they are formed into tubular rivets that are riveted or beading (m) the plate (i) is permanently attached to the switch housing (f) and at the same time establishes the metallic connection to the fixed contacts (j).

By moving the actuator (g) each to the side The desired switching is achieved with the stop surfaces of the slot (h).

The one explained in the description and shown in the figures Switch met with the simplest, inexpensive to manufacture components that required conditions.

Protection claims: 1.) Built-in switch with plug connection for devices for the optional switching of two heating elements in series or in parallel, in which the Circuit is closed or interrupted by a heat regulator, characterized in that that in the cavity (e) of the box-shaped switch housing (f) one in its longitudinal direction adjustable slide (c), in its recesses (b) movable under spring pressure standing contact pieces (a) are installed.

Claims (1)

2.) According to claim 1), characterized in that the cavity (e) of the switch housing (f) with the slide (c) stored in it from a plate (i), which carries the fixed contacts (j) with terminal lugs (k), is covered. 3.) According to claim 1) and 2) characterized in that in the walls of the switch housing (f) two connector pins (l) are attached by flanging them (m) the metallic connection with the fixed contacts (j), as well as the connection the resilient movable contact pieces (a) with the fixed contacts (j), furthermore the fastening of the plate (i) to the switch housing (f) is achieved. 4.) According to claim 1), 2) and 3) as shown and described. Fig. 1) shows the switch in plan (front side) Fig. 2) in longitudinal section A-A Fig. 3) shows the switch housing (f) with slide (c) (rear side) Fig. 4) shows the plate (i) with fixed contacts (j) (inside) Fig. 5) shows the plate (i) in section B-B Fig. 6) shows the switch housing (f) with slide (e) in section C-C.
